The purpose of this study is to numerically investigate the performance a solar physical surface absorption cooling system, in which activated carbon/methanol used as working pair, placed inside parabolic-shaped collector. governing mathematical model issue based on equations conservation mass, energy, and thermodynamics process. are discretized using fully implicit finite difference method, Fo...

In the last 30 years numerous attempts have been made to improve the efficiency of the parabolic collectors in the electric power production, although most of the studies have focused on the industrial production of thermoelectric power. This research focuses on the application of this concentrating solar thermal power in the unexplored field of building construction. To that end, a mechatronic...

This paper derives kinematic admissible bending moment – axial force (M-P) interaction relations for mild steel by considering strain hardening idealisations. Two models for strain hardening – Linear and parabolic have been considered, the parabolic model being closer to the experiments. The interaction relations can predict strains, which is not possible in a rigid, perfectly plastic idealizat...

Recent interest in small-scale solar thermal combined heat and power (CHP) power systems has coincided with demand growth for distributed electricity supplies in areas poorly served by centralized power stations. One potential technical approach to meeting this demand is the parabolic trough solar thermal collector coupled with an organic Rankine cycle (ORC) heat engine. The paper describes the...

Concentrating solar collectors systems and especially the mini Parabolic solar reflecting systems have been one of the main research topics due to their ability for integration into the building structure. In the present work the mini parabolic collector was considered in the East West orientation with such a slope so that the suns vector impinging normal to the parabola during the day. The beh...
